The T271 family is designed for 2 x Dn thread lengths, with an additional neck in order to bridge interference contours. The universal indexible insert threading milling cutter from Walter Tools is manufactured for high cutting rates along with high feeds per tooth. With adjustable coolant supply, the T271 has radial and axial coolant outlets.

The Application

The T271 tool can be used universally with ISO P,M,K,S and H up to 55 HRC. It is designed for threads with a nominal diameter from 24mm, with a pitch range of 1.5mm/18-4 TPI, threading a depth of up to 2.5 x Dn.

The Insert

The wear resistant universal grade WSM375 has easy cutting geometry with a positive basic shape with three cutting edges. Defined with a corner radii the inserts produces threads in accordance with various standards.

The Strategy

It is recommended that the thread be produced with a radial cut using synchronous milling. The programming radius can be determined using Walter GPS. Non cutting passes can be carried out without radius corrections.

Designed for modern multi-task machining the Sandvik Coromant CoroTurn Prime Twin-tool holder is intended for the complete machining of components that typically have a very slow tool changing time. The CoroTurn saves times when changing tools to increase machining utilisation and productivity.

Edge Utilisation

The CoroTurn Prime inserts have 3 edges per corner, each for longitudinal, facing and profiling resulting in the distribution of wear over a long edge and not just the insert tip. Moving heat away from the cutting zone, helps the sustainability of the insert substantially increasing the life of the insert.

External Turning Operations in all Directions

CoroTurn Prime A-type tool with three 35 degrees corners designed for light roughing,finishing and profiling.

The NC grooving system meets the highest of requirements, with extremely easy installation and maximum variety. The tool holder can be universally utilised due to the efficient changing of the individual components.

The modular grooving solution, can offer the same insert usage for internal and external machining, radial and face grooving. With a 2-10mm grooving width, the external machining offers a choice of groove depth potential, both for axial and radial grooving.

This solution offers a choice of both ground and sintered inserts with external shank sizes from 8x8 to 32x32 and an internal from 16mm minimum bore.

Note: Specific inserts are required for aluminium, full radius and circle grooves.
